 <p>This test checks whether DOM wrappers created by NodeIterator have their
 prototypes attached to the correct objects.  These nodes are from the child
 frame, so that's where their prototypes should be attached.</p>

 <p>Unfortunately, our implementation is buggy and we get wrappers from the
 parent frame here.  This test documents the bug so we'll know when we fix
 it.</p>
